I attempted to put many sizes of fan on the inside, but it would not fit in any situation. I don't use the trunk much at all. Everything is bolted to that plate. I know it's not the best, but it sucks out enough air.

The screen and such are near the driver (of course) lol. I have the screen setup like the Malibu, just carefully bolted to the dash, so the screen can be removed if necessary.

by the way it looks that fan is basically on the underside of the mobo. it doesnt seem like it would be that effective. why dont you try mounting the mobo inside the cubby hole instead of on the door. mount your hdd, psu and fan onto the door
